About the project

This website is a scientific platform centered on an interactive 3D map of solar activity, enabling the visualization and analysis of long-term observational data, including century-scale time series. The dataset is based primarily on measurements from instruments at the Kislovodsk Mountain Astronomical Station, complemented by archival data and historical reconstructions such as the Kodaikanal series. The project is developed by researchers in solar physics.

Work in progress — we welcome feedback and suggestions at iberalex@ya.ru
